English Title: Multicultural and Multi-ethnic Societies 1994. This paper argues that multicultural and multi-ethic societies pose new challenges. Given the magnitude of such phenomena it is essential to undertake a fresh examination of methods in social sciences. The author reviews the distinct foci of research, the principal themes through which the subject is tackled (fundamental concepts, analysis of contemporary societies and new forms of organization), as well as research methodology.
